Grosseteste (1168 – 1253) For Grosseteste, God was light. Understanding light meant understanding God. And since light followed the rules of Euclid, the way to light and to God was through geometry. John H. Lienhard - Biskop i Lincoln, England - Teologisk matematik

Agrippa (1486-1535) The Doctrines of Mathematicks are so necessary to, and have such an affinity with Magick, that they that do profess it without them, are quite out of the way, and labour in vain, and shall in no wise obtain their desired effect.

Monas Afrunding I know that many other powerful numbers may be produced out of our Quaternary, by virtue of arithmetic and the power of numbers. Yet he who does not understand that a very great obscurity has by this method been illuminated by those numbers which I have drawn out which have nature and distinction amongst such a multitude, will not be able to estimate their meaning, which is obscure and not to the point.
